Description of the basis for the determination of the recall population:

The recall population was determined based on manufacturing records. The production range reflects all possible vehicles that could experience the problem.

 

Description of how the vehicles being recalled differ from similar vehicles not included in the recall:

All vehicles produced within the dates of manufacture ranges specified above may be affected.  Vehicles produced outside the specified range were equipped with Anti-lock Braking System (ABS) modulators assembled with the appropriate amount of grease.

 

Identification of affected components:

Component:ABS Modulator
Part No.:CB500X: 57110-MKP-J81

CBR500R ABS: 57110-MKP-J01

Country of Origin:Japan
Manufacturer:Hitachi Astemo Ltd.

 

Defect description:

Excessive grease was applied to the O-ring of the reservoir piston of the ABS modulator. After continued use, foreign matter may adhere to the grease, which can be pinched in the check valve during braking and cause brake fluid to leak. If this occurs, the braking distance (without ABS activation) will increase, increasing the risk of a crash.

 

Chronology:

February – March 2021

Honda recalled certain 2020MY CRF1100A/D motorcycles globally for ABS modulators assembled with excessive grease. The U.S. market was not affected by this recall and NHTSA was notified in a Foreign Recall Notice (21F-022) submitted pursuant to 49 CFR 579.12. In parallel with the foreign recall, Honda continued its investigation into the impact of excessive grease application to the ABS modulator installed on other motorcycles as it was a common component and there was a report from the Italian market of a different motorcycle model with a similar complaint of reduced braking performance.

 

April – August 2021

Honda continued its investigation of several motorcycle models and the impact of excessive grease application on non-ABS braking performance. Based on certain characteristics such as vehicle weight, whether the excessive grease was applied to front or rear brake oil passages on the ABS modulator, and brake disc/caliper specifications, Honda confirmed the non-ABS braking performance for one family of motorcycles did not meet internal specifications.

 

August 26, 2021

Honda determined that a defect related to motor vehicle safety existed and decided to conduct a safety recall.

As of August 26, 2021, Honda has not received any warranty claims, field reports, or reports of crashes or injuries related to this issue for the US market.

 

Program for remedying the defect:

Registered owners of all affected vehicles will be contacted by mail and asked to bring their vehicle to an authorized Honda Powersports dealer. The dealer will visually inspect the lot number on the ABS modulator and replace affected ABS modulators for free.

Owners who have paid to have these repairs completed at their own expense will be eligible for reimbursement, in accord with the recall reimbursement plan on file with NHTSA.
